I have been having issues connect to the site mangadex which has recently been blocked by Verizon. I was wondering if Sonic went through the same route of deeming it malicious and blocking it for its users since the site went down the same time Verizon blocked it a couple of weeks ago.
No issue here accessing mangadex.org over Sonic. That domain doesn't appear to be blacklisted either.
Perhaps its being blocked locally by software, content filter, etc.?
